CONVERTIBLE SOFA-BED.

SPECIFICATION formingpart of Letters Patent No. 278,136, dated May 22, 1883.

Application filed April 16,1883. (No model.)

To all whom it may concern:

Be it known that I, Bonner E. HAMMER, a citizen of the United States, residing. in Philadelphia, Pennsylvania, have invented certain Improvements in Convertible Sofa Beds, of which the following is a specification.

The main object of my invention is to so construct a convertible sofa bed that the upholstered portions will be uppermost when the piece of furniture is opened out into the form of a double bed as well as when it is in the form of a sofa, and this object I attain by combining with the seat for the sofa a reversible section hinged to said seat, both seat and section being pivoted at their ends to hinged frame pieces, as more fully described hereinafterx.

In the accompanying drawings, Figure 1 is a side View of the piece of furniture in the form of a sofa; Fig. 2, a side view, showing it about being converted into a bed; Fig. 3, a

section showing it in the form of a bed, and

Fig. 4 a rear view of a'sofa. I p

The main frame A consists of the end pieces, a a, provided with legs and longitudinal bars a a. To the end pieces, a a, are hinged at b the portions B B, which form the arms of the sofa when the piece of furniture is used for that purpose, (Fig. 2,) while when it is used as a bed these pieces B are turned over on their hinges to stand on the floor and form part of the bedframe, as shown in Fig. 3. The arms B may be provided with any suitable form of springcatch, 1), to retain them in position, (Fig. 1.) These arms B carry the upholstered section D, which forms the seat of the sofa, and is pivoted to the arms by pivots d, (indicated by dotted lines in Figs. 1, and 3,) and to the rear of the seat-section is hinged the section E, which forms theback of the sofa when so used, (Figs. 1 and 4,) this back being supported atthe proper angle by bent arms F, carried by the pieces B. To the front of the seat-section D is hinged a similar upholstered section, D, so that in the sofa form of the sofa-bed the section D will be folded under the seat section with its upholstered side down, as indicated in Figs. 1 and 2.

This section D is pivoted to the end pieces, a

a, of the frame A, by means of the pivots d.

The back of the seat section D carries fixed leg-supports G G, which are connected by radius-rods g to legs H H, hinged to the rear of the back-section E.

When the piece of furniture is in use as a sofa the arms B rest on the end pieces, a, of the frame and are held by the catches b, and the section D, with its upholstered side uppermost, is in position for use as the seat, while the section D is folded underneath it, and the section E is supported at the proper angle by the arms or pins F, to form the back of the sofa,as shown in Fig. 1. To convert this into a bed the catches I) are released and the arms B are turned on their hinges b, (Fig.2,) to theposition shown in Fig. 3, carrying with them the seatsectiou D and back E, the latter as the seat rises coming to a horizontal position on the arms or supports F, Fig. 2, while the section D is turned over on its pivots until it assumes a horizontal position with its upholstered side uppermost in line with the two other sections, as shown in Fig.3. During these movements the seat-section D has maintained a nearly-horizontal position, as will be seen in the several views. As the back-section E assumes a horizontal position the legs H, owing to their radius-rodsg, will assume vertical positions, and

with the legs Gforin supports for the sections E and D of the sofa-bed.

I claim as my invention 1. The, combination of-the frame and back and seat sections of a sofa-bed with a section, D, hinged to the seat-section and pivoted to the frame, substantially as set forth.

2. The combination of the frame of a sofabed, hinged arm-pieces B,and back-section with a seat-section pivoted to the arm-pieces, and a section, D, pivoted to the frame and hinged to the seat-section, substantially as described.

3. The combination of the frame A of a sofabed and hinged arm-pieces B with a seat-section pivoted to the arm pieces, back section hinged to the seat-section, and section D, pivoted to the frame A, and also hinged to the seatsection, substantially as specified.

4. The combination of the frame A of a sofabed and hinged arm-pieces B, having supports F, with seat section D, pivoted to the armpieces, and back-section E, hinged to the said seat-section, substantially as described.

5. The combination of the frame and armpieces with seat-section, carrying legs G, and 5 hinged back, carrying hinged legs H, and re Witnesses:
